I use bowflex. I have the ultimate.
Its funny, so many BB's would think it would suck, but it doesnt.
I am able to do every exercise I used todo at golds gym very easily on the BF. I love it. I have gained a little over 26 pounds of LBM on my cycle + 100% workouts from bowflex.
Don't get me wrong, the gym is great(especially for getting motivation from others). I have a very busy schedule, and being able to workout at home is what I needed.
If you were to rate my satisfaction from 1-10, I would say 10.
